When you create an object with Shapeways, the order price is determined
by the actual printed volume (not by the model's bounding volume). An
easy way to save some money (well, sometimes a LOT of money!) is by
making your object hollow.
This short tutorial will explain the basics
of hollowing objects.
But true. Hollowing a piece can lead to dramatic economies... (like 900€)...
One of the cons about hollowing object is, of course that the poly number can double if you use the above method.
Using a polys decimation algorithm on the "inside" part can be wise... (even if it end up ugly, it's inside...)
yeah, your object sparked that triain of thought
